Univariate and Multivariate Surveillance Methods for Detecting Increases in Incidence Rates
… trials. Some have suggested adapting the scan statistic to monitor such rates and detect a rate increase as soon as possible after it occurs. Other methods could be used in prospective surveillance, such as the Bernoulli cumulative sum (CUSUM) technique. Issues involved in selecting …

Socio-spatial inequalities in late-stage cancer diagnosis in Illinois: spatiotemporal trends and methodological challenges
… the same period. The Bernoulli-based spatial scan statistic was used to detect clusters of late-to-early stage cancer ratios at the ZIP code level in Illinois during two periods: 1988 to 1992, and 1998 to 2002. Then the whole state was divided into three study region: Chicago city, Chicago …

Small and Stable Descriptors of Distributions for Geometric Statistical Problems
… represent distributions of points for geometric statistical problems. A <italic>coreset<italic> C is a small summary of a point set P such that if a certain statistic is computed on P and C, then the difference in the results is guaranteed to be bounded by a parameter ε. Two examples of …

Data Mining for Signal Detection of Targeted Therapy Related Drug Toxicity in Breast Cancer Patients
… Gamma Poisson Shrinker (GPS) with a tree-based scan statistic (TBSS). Using data from the Texas Cancer Registry and Surveillance, Epidemiology and End Results linked to Medicare from 2010-2014 we identified 8,949 patients with breast cancer treated with chemotherapy and 2,542 patients treated …

Analisi spaziale della longevità in Emilia-Romagna
… territoriali di forma regolare (spatial scan statistic, Kulldorff e Nagarwalla,1995; Kulldorff,1997, 1999) o dall’andamento geometrico “libero” (flexible scan statistic, Tango e Takahashi,2005; algoritmo genetico, Duczmal et al.,2007; greedy growth search, Yiannakoulias et al.,2007). Le …

Rebuilding Coastal Mississippi Following Hurricane Katrina: A Spatial and Temporal Analysis
… including descriptive and non-parametric statistics, visual multivariate analysis with the VIS-STAMP software package, and the spatial scan statistic SaTScan. The results of these analyses show that recovery is not occurring evenly in space or time across the Gulf Coast. The level and …

Multiscale decomposition of spatial lattice data for hotspot prediction
… with the multiscale Ht-index and the spatial scan statistic as a measure of saliency on the extracted pulses to detect significant hotspots. In the literature, geostatistical techniques such as Kriging has been used in epidemiology to interpolate disease cases from areal data to a continuous …

Developing A Geospatial Protocol For Coral Epizootiology
… geographic information systems (GIS) and spatial statistics, specifically the techniques used to map, detect, and spatially analyze disease epidemics, could be used to advance our understanding of coral reef health. Given that different types of spatial analysis, as well as different parameter …

The Emergence of Lyme Disease in Appalachia (2000-2019)
… Appalachia between 2000 and 2019 using spatial scan statistic. This type of analysis uses spatiotemporal information to quantify disease emergence and diffusion using retrospective case and location data within a GIS environment; hence it helped quantify the spatial distribution and diffusion of …

The Thin Green Line: Geographies of Ecoterrorism In the United States
… (GIS). A retrospective space-time permutation scan statistic was employed in SaTScan to determine where terrorism is clustered in both time and space. The majority of ecoterrorist incidents perpetrated in the United States showed a relatively stable, slowly increasing trend over time, with …

Real-time surveillance for evidence-based responses to suicide contagion and clustering
… quantitative Census data from the Central Statistics Office (CSO). The retrospective and prospective space-time scan statistics based on a discrete Poisson model was employed via the R software environment using the ‘rsatscan’ and ‘shiny’ packages to conduct the space-time cluster analysis …

Epidemiology of suburban deer
… Using the Bernoulli model in the space-time scan statistic in SaTScan®, a significant viral “hot spot” was revealed for JC virus in DP (p=0.009). A significant cluster for LAC virus was also found in DP (p=0.005). All clusters were independent of each other. Temporal patterns for JC virus …

The Spatial and Molecular Epidemiology of Lyme Disease in Eastern Ontario
Lyme disease is an emerging tick-borne illness in Canada, with human case numbers increasing 15- to 20-fold since Lyme disease became nationally notifiable in 2009 until the present. In Ontario, Canada's largest province by population, average Lyme disease incidence across the province is similar …
